Figure 1 is an external perspective view of a vacuum cleaner according to an embodiment of the present invention, Figure 2 is a rear view of the vacuum cleaner according to an embodiment of the present invention, and Figure 3 is an exploded perspective view of the vacuum cleaner according to an embodiment of the present invention. Figure 4 is a cross-sectional view of the vacuum cleaner according to an embodiment of the present invention, and Figure 5 is an external rear perspective view of the vacuum cleaner according to an embodiment of the present invention with the stick handle removed. Charging base 104 and support part 105 are not shown in Figure 5.

A stick handle 102 is detachably connected to the top of the stick body 101, and a suction mouth body 103 is detachably connected to the bottom of the stick body 101. The suction mouth body 103 is placed on a charging stand 104. A support part 105 extending upward is provided at the rear of the charging stand 104, and the support part 105 supports the rear of the stick body 101. In addition, an attachment device 106 such as a gap suction mouth is placed on the charging stand 104.

An opening 110 is formed in front of the stick body 101, and the handheld body 201 is removably housed in this opening 110. The handheld body 201 is equipped with a dust collection section 206, an electric blower 207, and a storage battery 208 as described below, and functions as a stick vacuum cleaner when the handheld body 201 is attached to the stick body 101, and functions as a handheld vacuum cleaner when the handheld body 201 is detached from the stick body 101. In other words, the stick vacuum cleaner and the handheld vacuum cleaner share the dust collection section 206, the electric blower 207, and the storage battery 208.

The stick handle 102 is equipped with a power switch 115, and pressing this power switch 115 drives the electric blower 207 and the rotating cleaning body 109 of the suction body 103.

A connection hole 102a is formed at the lower rear of the stick handle 102, penetrating downward. A connection pin 111 is provided at the upper rear of the stick body 101, which is inserted into the connection hole 102a. The connection pin 111 is biased backward, and by inserting this connection pin 111 into the connection hole 102a of the stick handle 102, the stick handle 102 is fixed to the stick body 101. When removing the stick handle 102 from the stick body 101, the connection pin 111 is pushed in and retracted from the position overlapping with the connection hole 102a, and then the stick handle 102 is pulled out (see Figure 5).

The lower part (front part) of the handy body 201 is provided with a suction pipe 202. The lower part of the stick body 101 is formed with a suction pipe receiving part 112 into which the suction pipe 202 is inserted, and by inserting the suction pipe 202 into the suction pipe receiving part 112, the movement of the lower part (front part) of the handy body 201 within the open part 110 is restricted. The suction pipe receiving part 112 is connected to the suction mouth body 103, and the suction pipe 202 and the suction mouth body 103 are connected to each other.

The stick body 101 is also provided with a handy removal button 113 at the top front. A handy body receiving part 203 is formed at the top (rear) of the handy body 201. The handy removal button 113 is biased downward by a spring, and the lower tip of the handy removal button 113 engages with the handy body receiving part 203, thereby fixing the handy body 201 attached to the opening part 110 to the stick body 101.

When removing the handy body 201 from the stick body 101, the handy removal button 113 is moved upward against the spring force, and the lower tip of the handy removal button 113 is retracted from the handy body receiving portion 203. In this way, the handy body 201 can be removed from the stick body 101.

The stick body 101 is provided with a suction body removal button 114 at the front of the lower part. The connection tube 107 of the suction body 103 is provided with a connection hook 107a. The suction body removal button 114 is biased forward by a spring, and a part of the suction body removal button 114 fits into the connection hook 107a to fix the suction body 103 to the stick body 101. The suction body 103 is provided with a rotating cleaning body 109 that is rotated by an electric motor (not shown). The rotating cleaning body 109 acts to sweep in dust from the cleaning surface, such as the floor surface. Note that the rotating cleaning body 109 is not an essential component, and dust may be sucked in only by the suction force of the electric blower 207 without the rotating cleaning body 109. The rotating cleaning body 109 may also be rotated by the suction force generated by the electric blower 207, rather than by an electric motor.

The support part 105 has a protrusion 105a that protrudes upward at the front. A protrusion receiving part 108 is formed at the rear of the stick body 101, and by inserting this protrusion receiving part 108 into the protrusion 105a, the vacuum cleaner 100 (stick body 101) is supported in an upright position on the charging stand 104.

Next, the configuration of the handy body 201 will be described. Figures 6 and 7 are external perspective views of the handy body 201 according to an embodiment of the present invention, Figure 8 is a cross-sectional view cut in the front-rear direction of the handy body 201 according to an embodiment of the present invention, and Figure 9 is an external perspective view showing the brush member according to an embodiment of the present invention.

The handy body 201 functions as a handy vacuum cleaner. The handy body 201 is equipped with a handy handle 204 at the upper rear, a power switch 205 installed in front of the handy handle 204, a dust collection unit 206 detachably attached to the front of the handy body 201, and a suction pipe 202 connected to the dust collection unit 206.

Inside the handheld main body 201, there is an electric blower 207 that generates suction force, a storage battery 208 that supplies power to the electric blower 207, and a control device 209 that controls the storage battery 208 and the electric blower 207.

A brush member 210 is provided in front of the suction pipe 202. The brush member 210 includes a brush 210a that comes into contact with the surface to be cleaned, a brush support part 210b that serves as a base for attaching the brush 210a, a pair of arms 210c that extend from the brush support part 210b toward the side opposite the brush and are formed to sandwich the suction pipe 202 from both sides, and a rotation restriction part 210d that is attached to the brush support part 210b and restricts the rotation of the brush support part 210b.

The brush member 210 is supported rotatably relative to the suction pipe 202. The pair of arms 210c are provided with a rotating shaft 210c1, which is inserted into a small hole (not shown) formed in the suction pipe 202, causing the brush member 210 to rotate relative to the suction pipe 202.

When using the brush member 210 as a handheld vacuum cleaner, the brush member 210 is rotated so that the brush member 210 is positioned on the extension of the suction pipe 202. When the brush member 210 is rotated, the rotation restricting portion 210d comes into contact with the front end of the suction pipe 202, restricting the rotation of the brush member 210. The brush member 210 is inclined so that it faces downward relative to the forward extension direction of the suction pipe 202. When the brush member 210 is in an inclined state, the lower side of the brush member 210 is open, so the flow path of the suction pipe 202 is not blocked.

When storing the brush member 210, the brush member 210 is rotated so that the brush member 210 faces the rear of the suction pipe 202. In other words, the brush member 210 rotates so that it can retract from the extension of the suction pipe 202. When the brush member 210 is rotated, the arm portion 210c of the brush member 210 comes into contact with the rotation restriction protrusion 202a formed on the side of the suction pipe 202, and the rotation of the brush member 210 is restricted. In this way, the brush member 210 retracts from the front end of the suction pipe 202.

When the brush member 210 is retracted from the front end of the suction pipe 202, an attachment device 106 such as a gap suction nozzle can be attached to the front end of the suction pipe 202. In addition to the gap suction nozzle, an extension tube (not shown) can be connected. The suction pipe 202 is provided with a well-known clamp hook 211, which allows the extension tube to be connected and fixed. Furthermore, the suction body 103 or another suction body (second suction body) can be connected to the front end of the extension tube.

In other words, when the extension tube and the second suction body are connected to the handheld main body 201 of this embodiment, the handheld main body 201 can be used as a stick vacuum cleaner (not shown) in the shape of a handheld device held by the user. In addition, by supplying power to the tip of the suction pipe 202, it is possible to use accessories that incorporate an electrically driven motor or LED, or to drive the rotating brush of the second suction body by driving the motor built into the second suction body via the conductive parts inside the extension tube.

In this embodiment, the handheld body 201 is equipped with a suction pipe 202, and an extension tube or the like can be connected to this suction pipe 202, improving the ease of use of the vacuum cleaner.

When attaching the handy body 201 to the stick body 101, the brush member 210 is retracted from the front end of the suction pipe 202. When attaching the handy body 201 to the stick body 101, first, the suction pipe 202 is inserted into the suction pipe receiving portion 112, and then the handy handle 204 side is pushed into the stick body 101. Then, the lower end of the handy removal button 113 fits into the handy body receiving portion 203, and the handy body 201 is attached to the stick body 101.

When the brush member 210 is retracted from the front end of the suction pipe 202, it protrudes rearward (downward) from the surface of the suction pipe 202. When attached to the stick body 101 in this state, the brush member 210 and the stick body 101 come into contact. Therefore, in this embodiment, contact between the brush member 210 and the stick body 101 is avoided as follows.

As shown in FIG. 5, an opening 116 is formed at the rear of the stick body 101, penetrating the stick body 101. When the handy body 201 is attached to the stick body 101, a portion of the brush member 210 protrudes from the opening 116. That is, in this embodiment, when the handy body 201 is attached to the stick body 101, the opening 116 is provided to prevent contact between the brush member 210 and the stick body 101. By configuring in this manner, in this embodiment, the handy body 201 can be smoothly attached to the stick body 101.

Next, the attachment/detachment configuration of the handy main body 201 and the dust collection unit 206 will be described with reference to Figures 8, 10, and 11. Figure 10 is an external perspective view showing the state in which the dust collection unit has been removed from the handy main body according to the embodiment of the present invention, and Figure 11 is an external perspective view of the handy main body according to the embodiment of the present invention, viewed obliquely from below. Figure 11 shows the state in which the seal packing has been removed.

The dust collection unit 206 is provided at the upper rear with a detachment button 212 for removing the dust collection unit 206 from the handy body 201. The detachment button 212 is biased rearward (toward the handy body 201) by a spring, and the claw portion 212a of the detachment button 212 enters the handy body 201 to hold the rear side of the dust collection unit 206. A hook portion 213 (Figure 8) is formed at the lower front of the dust collection unit 206. A receiver portion 214 for receiving the hook portion 213 is formed above the suction pipe 202. By hooking the hook portion 213 onto the receiver portion 214, the front of the dust collection unit 206 is held by the handy body 201, and the rear of the dust collection unit 206 is held by the handy body 201 by the detachment button 212.

Furthermore, an outlet 215 that communicates with the dust collection section 206 is formed above the suction pipe 202. The dust-laden air that flows in from the suction pipe 202 is discharged from the outlet 215 and flows into the dust collection section 206. When used as a stick vacuum cleaner, the dust-laden air that passes through the suction body 103, the connecting tube 107, and the suction pipe 202 is discharged from the outlet 215 and flows into the dust collection section 206.

The discharge port 215 is formed shifted to the left or right from the center line C1 of the suction pipe 202. In this embodiment, the discharge port 215 is shifted to the right when viewed from the viewpoint of a user using it as a handheld vacuum cleaner. A seal packing 216 is attached to the discharge port 215 to ensure airtightness between it and the dust collection unit 206. The seal packing 216 has a lip portion 216a that maintains airtightness around the opening of the discharge port 215, and a valve body 216b that opens and closes the discharge port 215. The lip portion 216a and the valve body 216b are rotatably connected by a rotating portion 216c, and the valve body 216b opens and closes the discharge port 215 with the rotating portion 216c as an axis.

When the suction force of the electric blower 207 is generated, the valve body 216b rotates from the suction pipe 202 toward the dust collection section 206. In addition, on the upstream side (the suction pipe 202 side) of the valve body 216b, a plurality of ribs 216d protruding from the surface of the valve body 216b are formed. The plurality of ribs 216d are formed so as to extend from the rotating section 216c toward the counter-rotating section. In other words, the plurality of ribs 216d are formed so as to follow the flow of air.

In this embodiment, multiple ribs 216d are formed on the upstream side of the valve body 216b, ensuring the rigidity of the valve body 216b and making it easier for the valve body 216b to open around the pivot 216c as the pivot. In addition, multiple ribs 216d are arranged along the air flow, allowing dust-containing air that collides with the valve body 216b to flow smoothly toward the dust collection section 206. In addition, when the electric blower 207 is stopped and no suction force is being generated, the weight of the multiple ribs 216d causes the valve body 216b to operate to close the discharge port 215, preventing dust from spilling out of the dust collection section 206.

Next, the configuration of the dust collection section 206 will be described using Figures 12 to 15. The description of Figures 12 to 15 will be based on the case where it is used as a stick vacuum cleaner. In this case, the dust collection case 220 side is the bottom, the filter housing section 223 side is the top, the attachment/detachment button 212 side is the front, and the inlet 227 side is the rear. When it is used as a handheld vacuum cleaner, the dust collection case 220 side is the front, the filter housing section 223 side is the rear, the attachment/detachment button 212 side is the top, and the inlet 227 side is the bottom.

Figure 12 is an exploded perspective view of the dust collection unit according to the embodiment of the present invention, Figure 13 is an external perspective view of the dust collection unit according to the embodiment of the present invention as seen from the front, Figure 14 is a cross-sectional view of the dust collection unit according to the embodiment of the present invention as seen from the left side, and Figure 15 is a view of the dust collection unit according to the embodiment of the present invention as seen from the rear.

The dust collection section 206 includes a cylindrical dust collection case 220 with a bottom for collecting dust, an umbrella section 221 mounted in the dust collection case 220, an inner tube 222 connected to the umbrella section 221 and mounted in the dust collection case 220, a cylindrical filter housing section 223 with the inner tube 222 at the bottom and housing a filter, a first dust trapping filter 224 housed in the filter housing section 223, and a second dust trapping filter 225 housed in the filter housing section 223 and arranged downstream of the first dust trapping filter 224. The first dust trapping filter 224 is made of sponge and can be washed with water. The second dust trapping filter 225 is folded in a pleated shape (pleats) to expand the ventilation area, and is bonded to a circular frame 225a. In this embodiment, two dust trapping filters, the first dust trapping filter 224 and the second dust trapping filter 225, are provided, but there may be only one dust trapping filter.

The upper side (downstream side) of the second dust filter 225 faces the suction port of the electric blower 207. A cleaning brush 226 for cleaning the second dust filter 225 is removably attached to the outer periphery of the dust collection case 220. The cleaning brush 226 is provided with bristles 226a, and the bristles 226a are used to clean dust adhering to the second dust filter 225, for example.

The filter housing section 223 has a partition wall 223a that supports the first dust filter 224, and an opening 223b formed in the center of the partition wall 223a. An inner tube 222 with multiple support posts 222a is fixed around the periphery of the opening 223b. A breathable mesh filter 222b is provided between adjacent support posts 222a of the inner tube 222. The inner tube 222 also has a circular inner tube frame 222c that connects the multiple support posts 222a. The outer periphery of the inner tube frame 222c has a rail protrusion 222d that protrudes toward the outer periphery and has multiple cutout portions 222d1 that are partially cut out.

A circular annular wall 221a is formed on the upper side (inner tube 222 side) of the umbrella portion 221, and multiple protrusions 221b protruding inward are formed on the inner circumference of this annular wall 221a. When connecting the umbrella portion 221 and the inner tube 222, the multiple protrusions 221b on the umbrella portion 221 side are aligned with the positions of the multiple cutouts 222d1 on the inner tube 222 side, and the multiple protrusions 221b are inserted into the multiple cutouts 222d1. Then, the umbrella portion 221 is rotated to the right or left. The multiple protrusions 221b are positioned above the position of the rail protrusions 222d (inner tube 222 side), and the umbrella portion 221 and the inner tube 222 are connected. When removing the umbrella portion 221 from the inner cylinder 222, rotate the umbrella portion 221 to the right or left, align the multiple protrusions 221b with the multiple cutout portions 222d1, and pull out the umbrella portion 221.

The umbrella portion 221 is provided with a cross-shaped bridge portion 221c arranged to cross the inside of the umbrella portion 221, and further provided with a cross-shaped cross rib 221d extending from the bridge portion 221c toward the bottom of the dust collection case 220. The tip of the cross rib 221d is formed in a straight line so as to follow the bottom side of the dust collection case 220, and both ends of the straight line are formed in an arc shape. As described later, the cross rib 221d compresses the dust by the force of the collision when dust swirling in the dust collection case 220 collides with the cross rib 221d. In addition, a mesh filter 221e is provided between adjacent cross-shaped bridge portions 221c. In addition, a circular protrusion portion 221f protruding toward the dust collection case 220 is formed on the outer periphery of the umbrella portion 221. The shape of the protrusion portion 221f is the same as the inner periphery shape of the dust collection case 220. In addition, the protrusion 221f is located below the inlet 227 and below the vertical halfway point of the dust collection case 220.

The filter housing 223 and the dust collection case 220 are configured to be detachable. On the outer periphery of the filter housing 223, multiple protrusions 223c are formed protruding toward the outer periphery. On the other hand, on the inner periphery of the dust collection case 220, multiple upper protrusions 220a and lower protrusions 220b are formed protruding toward the inner periphery. The upper protrusions 220a have multiple cutout portions 220c that are partially cut out, and are formed to have a shorter circumferential length than the lower protrusions 220b. The upper protrusions 220a and lower protrusions 220b are formed so that they partially overlap on the open side of the dust collection case 220.

When connecting the filter housing 223 and the dust collection case 220, the multiple notches 220c on the dust collection case 220 are aligned with the multiple protrusions 223c on the filter housing 223, and the multiple protrusions 223c are inserted into the multiple notches 220c. The dust collection case 220 is then rotated to the right or left. The multiple protrusions 223c are inserted between the upper protrusion 220a and the lower protrusion 220b, and the filter housing 223 and the dust collection case 220 are connected. When removing the dust collection case 220 from the filter housing 223, the dust collection case 220 is rotated to the right or left, the multiple protrusions 223c are aligned with the multiple notches 220c, and the dust collection case 220 is pulled out.

The dust collection case 220 is formed with an inlet 227 through which dust-laden air flows in. The inlet 227 is connected to the outlet 215 of the suction pipe 202 via a seal packing 216. The inlet 227 is positioned offset from the center line C2 of the dust collection section 206 (Figure 15). In this embodiment, the inlet 227 is positioned offset to the right when viewed from the perspective of a user using the vacuum cleaner as a stick vacuum cleaner or a handheld vacuum cleaner.

When the user presses the power switch 115 or 205 when using the vacuum cleaner as a stick vacuum cleaner or a handheld vacuum cleaner, the electric blower 207 is driven to generate suction force. The air containing dust passes through the suction pipe 202 or suction pipe from the suction body 103 and is discharged from the discharge port 215 to the dust collection section 206 side. The air containing dust discharged from the discharge port 215 passes through the inlet 227 and flows into the dust collection case 220. Since the inlet 227 is positioned at a position offset from the center line C2 of the dust collection section 206, the air containing dust that flows in from the inlet 227 flows along the inner surface of the dust collection case 220 and becomes a swirling flow at the position of the inner cylinder 222 (broken line in FIG. 14). Some of the air from which dust has been removed passes through the mesh filter 222b of the inner cylinder 222, and then the first dust trapping filter 224 and the second dust trapping filter 225 remove fine dust particles, and is then sucked into the electric blower 207.

The dust flowing as a swirling flow collides with the inner wall of the dust collection case 220 due to centrifugal action, passes through the gap between the protrusion 221f and the dust collection case 220, and moves to the bottom of the dust collection case 220. The dust that has moved to the bottom of the dust collection case 220 collides with the cross rib 221d, which suppresses the swirling flow, and the dust is compressed by suction force. The air from which the dust has been separated passes through the mesh filter 221e arranged between the bridge parts 221c, and this mesh filter 221e captures light dust such as cotton dust and fine dust. The dust filtered by the mesh filter 221e is compressed by suction force. The air that has passed through the mesh filter 221e is further passed through the first dust trapping filter 224 and the second dust trapping filter 225 to remove fine dust, and is sucked into the electric blower 207.

In this embodiment, the shape of the protrusion 221f is the same as the inner peripheral shape of the dust collection case 220. Therefore, the gap between the protrusion 221f and the dust collection case 220 is uniform, which prevents loss of the swirling flow and improves the dust separation function. In addition, the protrusion 221f is located below the inlet 227 (the bottom side of the dust collection case 220) and is located below the vertical half position of the dust collection case 220, so that dust that passes through the gap between the protrusion 221f and the dust collection case 220 can be prevented from flowing back through the gap and floating up toward the inner cylinder 222.

The first opening 236 is also connected to an exhaust passage 238 (Figure 8) of the electric blower 207.

When the electric blower 207 starts operating, the exhaust air flows into the exhaust passage 238 and then into the first opening 236 located downstream of the exhaust passage 238. The exhaust air that flows into the first opening 236 flows along the outer periphery of the storage battery 208 and is discharged from the second opening 237.

In this embodiment, the storage battery unit 230 is provided with a first opening 236 and a second opening 237, and the exhaust air from the electric blower 207 is allowed to flow through, thereby suppressing the temperature rise of the storage battery 208.

When charging the storage battery 208, the stick vacuum cleaner is placed on the charging stand 104 as shown in Figures 1 and 4.

In this embodiment, the control board 233 is equipped with a function for controlling the main body and the battery, but the board that controls the main body may be provided as a separate component external to the storage battery unit 230 and mounted on the handheld main body 201, etc.

The charging stand 104 is connected to a commercial power source (not shown). The charging stand 104 is provided with a power supply terminal 120 as shown in FIG. 3. The stick body 101 is provided with a power receiving terminal 121 that contacts the power supply terminal 120 as shown in FIG. 5. Furthermore, the open portion 110 of the stick body 101 is provided with a power supply terminal 122. The power receiving terminal 121 and the power supply terminal 122 are connected by a power cord (not shown). The handheld body 201 is provided with a power receiving terminal 240 that contacts the power supply terminal 122 as shown in FIG. 11. The power receiving terminal 240 is connected to the storage battery 208.

Then, when the handheld body 201 is attached to the open portion 110 of the stick body 101 and the stick body 101 is placed on the charging stand, the power receiving terminal 240 and the power supply terminal 122, and the power receiving terminal 121 and the power supply terminal 120 are connected, the storage battery 208 and the power supply terminal 120 are electrically connected, and the storage battery 208 is charged.
